A book chapter arguing that cities will need internal food production to meet demand from growing urban populations and to avoid congestion, pollution and unaffordable food prices, and examining vertical farming — using hydroponics, aeroponics and aquaponics — as an approach suited to urban settings where land is limited and expensive. After reviewing these technologies and project prototypes, the chapter closes by stating that economic feasibility, building codes and regulations, and a lack of expertise remain major obstacles to implementing the vertical farm.

Gifford Park, a neighborhood in Omaha, Nebraska, United States, has been recreating itself through urban agriculture like many neighborhoods across the country. This case study conceptualizes urban agriculture as a "place ballet" — describing interactions between places and bodies — extending the idea that places can function as spatial arguments. The analysis found that urban agriculture reveals a complex material argument about the positive impacts places and bodies can have on communities and their members, while simultaneously overlooking the economic and racial privileges inherent in these efforts, and concludes that the place-ballet concept itself carries its own implications of economic and racial privilege.

In Nairobi, Kenya, stratified random sampling, field surveys and questionnaires were used to identify existing water sources and wastewater treatment systems and their reuse status, in an investigation of the potential for eco-friendly urban and peri-urban agriculture (EcoUPA). Of the 300 respondents interviewed, only 66 (22%) reused wastewater, and only 54 of those reused it for crop production. Ninety-eight respondents (33%) wanted information on wastewater treatment systems allowing reuse, and 124 (41%) were willing to pay for a new system. The findings indicate that limited urban water sources constrain the spread of urban and peri-urban agriculture.

Alexey Valerevich Vasilchikov · Eurasian Law Journal · Russia

A study of urban agglomeration development trends in the regions of the Russian Federation, drawing on analyses from various Russian sociological research schools, examines the differentiation between cities — including million-plus cities — competing for natural, demographic, financial, and investment resources. It finds that large agglomerations act as monopolists that in many cases hinder the successful development of medium-sized and especially small Russian cities, further worsening inequality in living standards and quality of life across localities throughout the Russian Federation.

Agustina Cavalanti · El Barrio Pueyrredón · Argentina

An article reporting that urban gardeners in the Autonomous City of Buenos Aires warn a newly passed urban agriculture law 'conceals the possibility of using public land for private profit.' It states the bill was passed by the ruling majority without room for debate, and criticizes Article 8, which lets any natural or legal person, public or private, apply for permits to develop gardens. A citizen group, 'El Reciclador,' had proposed an alternative emphasizing state or nonprofit management and an educational focus, which was not adopted. Gardeners in the Villa Pueyrredón neighborhood distributed 200 seedlings in protest.

This paper argues that community gardens should be a prioritized element of green infrastructure to improve cities' adaptation to climate change. Community gardens can reduce urban heat islands, provide ecosystem services, and increase stormwater retention. However, a qualitative analysis of 18 policy documents for Baltimore, Chicago, and New York City, U.S.A., found that green infrastructure for climate change adaptation prioritizes rain gardens, bioswales, and green roofs, but seldom acknowledges the role of community gardens.

Michael Carolan · Journal of the American Planning Association · United States

This 2019 study, based on 82 interviews in Denver, New York, and San Francisco, investigated how traditional and digital urban agriculture converge and diverge regarding land use and gentrification. It found that both digital and traditional urban farming systems are linked to gentrification and inequitable land use patterns. Digital urban farming systems also operate in a regulatory gray area, with their "digital" aspects used to gain more zoning permission than traditional urban agriculture.

Alessio Russo, Giuseppe T. Cirella · Humanities and Social Sciences Communications · Global

This comment examines "edible urbanism 5.0," noting that urban and peri-urban agriculture can have negative effects on city ecosystems, which urbanists and planners have largely overlooked. It highlights the need for a concept that considers trade-offs between ecosystem services and disservices, especially given current unsustainable industrial intensive farming. Edible urbanism aims to integrate food security, resilience, and social inclusion through edible green infrastructure and modern food production.

Leelanayagi Ramalingam, Juwaidah Sharifuddin, Zainal Abidin Mohamed, Fazlin Ali · International Social Science Journal · Malaysia (Klang Valley)

This study analyzed data from 375 volunteers in Community-based Urban Agriculture Programmes in Klang Valley, Malaysia, to determine the relationship between motivation and satisfaction. It found that volunteer satisfaction was primarily influenced by external factors like campaigns, support groups, extension departments, community, and government policy, followed by love of farming, social referents, and values. The program faces problems in attracting and retaining enough volunteers, indicating a governance challenge for sustainability.

Sarah E. Cramer, Anna Ball · Journal of Agricultural Education · United States

This qualitative case study in the United States examined a school garden program transitioning from non-profit to public school district control, conceptualizing this as a shift from a non-formal to a formal education paradigm. The research explored tensions between constructivist, non-formal educational philosophies and standardized, formal education within school garden settings. The findings indicate challenges in integrating non-formal learning into formal public education structures, arguing for broader legitimation of garden-based learning in curriculum.

Christine Aubry, Nastaran Manouchehri · OpenEdition (OpenEdition) · France (Paris)

Urban and peri-urban agriculture is exposed to various forms of pollution related to cultivation methods and urban air and soil quality, with different crop types exhibiting varied reactions to pollutants. The T4P and REFUGE programs on urban farms in the Paris region, and the ADURAA and QUALISANN programs studying vegetable-growing in Antananarivo, Madagascar, aim to assess health risks and oversee practices using methodological frameworks.

Giszell Dymond Weather · Carolina Digital Repository (University of North Carolina at Chapel Hill) · United States

A 7-month study of the Angier Avenue Neighborhood Farm in East Durham, a predominantly Black area, found that Black residents rarely participate in farm activities. This research, based on participant observation, interviews, and food systems research, theorizes the relationship between urban farming and gentrification, arguing that equitable community food projects must incorporate local Black residents' cultures and histories to be sustainable.

오익근, 서정아, 장승옥 · 한국지역개발학회지 · South Korea

A focus group interview with young urban farmers in Daegu, South Korea, explored job creation through urban farming. Participants perceived farming as physically demanding and unrewarding, despite seeing urban farming as a promising industry for job creation. They also noted a lack of national support policies and difficulties in participation. A contradiction was identified between the young farmers' desire to adopt labor-saving new technologies and the goal of creating jobs through traditional farming.

Arantza Elena Sanchez Gutierrez · · Mexico

In Querétaro Municipality, Mexico, a strategy was designed and implemented to increase and incentivize the use of urban agriculture. Previous strategies implemented in Mexico had resulted in low participation and abandonment of practice due due to low interest from inhabitants and a lack of will to follow through on plans. This qualitative research analyzed the causes of these failures using User-Centered Design tools and Design Thinking. Findings showed that a "strategy of appropriation," emphasizing a sense of belonging, well-being, and commitment, resulted in an increase in this variable, which influences the abandonment of agricultural practices.

Maurice Dasylva, Ngor Ndour, Bienvenu Sambou, Sara Danielle Dieng · European Scientific Journal ESJ · Senegal (Ziguinchor)

In Ziguinchor, Senegal, the peri-urban rice farming system contributes to food security but is ignored by decision-makers and suffers from urbanization and physicochemical changes in rice field soils. An agronomic diagnosis, based on 180 yield squares (1/4m side) installed in 4 peri-urban valleys, showed average yields of 4.79 ± 0.35 t.ha-1. However, urbanization, silting, acidification, and progressive salinization of soils are the main limiting factors for this production system.

Emmanuel Patroba Mhache, Elna Lyamuya · Huria Journal of the Open University of Tanzania · Tanzania (Dar es Salaam)

This review paper examined the role of urban agriculture in alleviating poverty for women in the Dar es Salaam Region, Tanzania. It found that women's participation in urban agriculture contributes to food security, increases household income (average net income Tshs 58,356.2 per month), offers employment, and reduces poverty. However, numerous bottlenecks hinder women's involvement in urban agriculture, including poor markets, water shortage, land shortage, seed unavailability, lack of capital, lack of government support, crude working tools, lack of water pumping machines for irrigation, poor storage facilities, and lack of agricultural extension services.

Chiara Certomà, Martin Sondermann, Susan Noori · Manchester University Press eBooks · Europe

This chapter critically analyzes the relationship between urban gardening and socio-spatial justice, exploring whether and how urban gardening practices can tackle social and spatial injustices. Urban gardening points out less visible sides of urban governance and planning, unveiling different forms of power, dominance, and resistance to the unequal distribution of benefits and burdens in space. The analysis questions the contradictions in the constitution of urban spaces and their capability to mitigate material, political, and social exclusions, unfairness, and inequalities.

Milagros de la Caridad Mata Varela, Johana Meza Salvatierra, Ana Yilian Santana Mata · DOAJ (DOAJ: Directory of Open Access Journals) · Global

This research evaluated investment project management in urban agriculture through its life cycle, applying eighteen indicators and a management index. The study concluded that an agroecological farm development project exhibited economic inefficiency during its first two years of operation due to an imbalance between income and expenses, preventing high management values.

Efrat Eizenberg · Manchester University Press eBooks · Global

This concluding chapter reviews the literature on urban gardening, outlining both enthusiastic approaches that focus on its transformative potential and critical approaches that analyze it as greenwash or a strategy of neoliberal development. The chapter discusses how the book's chapters address this gap in understanding urban gardening and the resolutions and new directions they offer. It states that urban gardening is sometimes analyzed as a form of greenwash and a strategy of neoliberal development.

Daiara Batista Mendes · Geografia em Atos (Online) · Brazil (Pirapozinho)

This article identifies the potentialities of urban agriculture in Pirapozinho, São Paulo, focusing on food and economic use. Based on field research and interviews, the study found that urban agriculture provides quick access to quality products and fosters close farmer-consumer links. However, it also found that urban agricultural practices have not received due governmental attention at national or local scales, despite their potential.

Rainer Einzenberger, Michaela Hochmuth · Digital Commons - Lingnan (Lingnan University) · China (Hong Kong)

An interview with Professor Kin-Chi Lau was conducted in March 2015 regarding the Urban Gardening Project at Lingnan University of Hong Kong. The interview portrayed the project's history, structures, and organizational characteristics, focusing on the challenges and difficulties participants faced in realizing the project.

Nadine Appelhans, Sabine Baumgart · · Morocco

An analysis of documents related to planning and agriculture and interviews with experts in Morocco indicated that urban and rural issues were treated as separate areas. Urban development affects daily travel distances as urban expansion changes distances between cultivated land and dwelling places. Data from Morocco show a lack of serious support for urban agriculture and animal husbandry in expanding urban agglomerations.

Meng YE, Tomohiko Yoshida · Urban and Regional Planning Review · China (Beijing)

This study examined user evaluations of allotment gardens in Beijing, China, where demand is rising. The overall evaluation was between good and general, with high marks for landscape and facilities but low marks for service, guidance, agricultural festival activities, rent, sanitary facilities, and skilled labor. The consortium operation mode received the best evaluation, while the individual mode had the lowest.

Nineteen qualitative expert interviews were conducted to identify perceptions of sustainability, social acceptability, and ethical aspects of new urban food production approaches. While major perceived benefits included educational effects and efficient resource use, significant conflicts involved negative side-effects, legal constraints, and high investment costs. Acceptance barriers were largely tied to the "unknown," encompassing a lack of understanding of new approaches, uncertainty about benefits, health risk concerns, unfamiliarity with products, and ethical doubts about animal welfare. The study concluded that adapting the unsuitable regulatory framework, which discourages investors, is a crucial first step to foster dissemination of urban food production approaches.

A study mapped and quantified urban growth and land use in Córdoba, Argentina's Green Belt. Using remote sensing and GIS, it evaluated urban growth between 1974 and 2014 and land use in peri-urban and rural areas in 2015. The study revealed a 46.5% urban area growth over nearly 40 years, alongside an increase in farm plot size, indicating land ownership concentration and a reduced number of producers. This transformation highlights a conflict between peri-urban horticulture, industrial agriculture, and urban development.
